SecureDelete can wipe data stored in the Windows page file at shutdown, the Windows page file is where the operating system stores information when and if it runs out of volatile RAM memory, all kind of confidential data could be found there, including passwords, computer forensics suites are capable of extracting page file data, Windows page file, also known as swap file, can not be manually deleted as it is part of the operating system, this is the reason why it has to be wiped at shutdown or boot up. If you choose to wipe your Windows page file the shutdown process will take much longer than usual, it’s probably best to only enable this option only once in a while and if you have enough RAM in your computer you don’t need to wipe Windows page file as it will be empty.
